To all whom it may concern:

Be it knownthat I, CHARLES H. MUoKEN- HIRN, a citizen of the United States, residing at Detroit, in the county of WVayneand State of Michigan, have invented certain new and useful Improvements in Soil-Pipe.-

Sealing Devices for, Closet-Bowls and the like, of which the following is a specification,

reference being .had therein to the accompanying drawing.

This invention relates to an improved means for effecting an air-tight connection between a drain pipe or soil pipe of a closet bowl and its fixture.

Heretofore many attempts have been made to provide a close joint between the so-called bowlflange and soil pipe coupling, but such attempts have been more or less unsatisfactory in that they do not maintain the proper sealed joint. In some States, what is termed a metal-to-metal joint is required, as distinguished from a fibrous packing. Such requirements demand the use of a soft metal, such as lead, or a proper alloy and require the application of the packing to the joint or parts in a manner which will maintain a constant and uniform sealed contact.

The present invention is designed to 'provide a close metallic joint between the metallic nipple and the flange of' the closet bowl. It is to be understood, however, that .whilethe invention is designed more particularly for the purposes stated, its use can be extended into other fields where packing joints are employed, such as joints used in lavatories, basins, tubs, sinks, etc. j

Theinvention is shown in an ascertained successful embodimen in the drawing wherein, 1 i

Figure 1 represents a sectional view of the device,

Fig, 2 is a plan view of the adjustable ringyand,

Fig. 3 is a view similar to Fig. 1, slightly modified. A

The soil pipecoupling or. .end part is designated at A, the same being shown for convenience as passing upthrough an opening in the floor'B. In this'conneotion it is to be understood that the various parts may be arranged horizontally when intended for use in connection with a side supported bowl or basin. In such a suggested use the part B' will represent the partition or wall; 0 represents the outlet to the bowl which has a flanged lower end (1C, The inner edge ofthe flzingeG is providedzwith a marginaldepending rib C while" the flange between the rib and the bowl throat is reinforced or thickened to add strength, the inner face of which is beveled or inclined, the said in clined or beveled portion being relatively long, as at C to permit a very effective clamping between the outlet of the bowl and Patented Mar. 6, 1917.

the nipple to be presently described. Into the chamber formed by the rib G the upper end of the nipple A projects, as shown. The; diameter of the nipple, however, isless than the'interior diameter of the cavity formed by the rib C as clearly shown.

Secured to the floor,,in the usual manner, is a base or connecting platerD, towhich is secured, by any convenient means, two hollow post members E, the upper outer ends of which are threaded to receive the nuts 6. These post members project through openings in the flange C and by the employment of the nuts. on the threaded ends thereof, the bowl'is clamped inposition on the floor or supporting part. above the securing plate D is a ring or gasket F, through which the upper end of the nipple A projects. The inner wall of this ring or gasket is closely adjacent the nipple while the innermost portion is reinforced and strengthened against twisting or turning by anoutwardly extending lip or flange part F. This rib part of the gland or ring, when in proper position, is located in the space between the inclined wall of the flange part of the bowl and the end of the nipple, as shown in Fig. 1. At this point a soft metallic washer G is interposed. The gland or ringF, is provided, conveniently at diametrically opposite points, with outstanding studs H, fitted in the hollow posts or securing parts E in any well known manner. The upper parts of the posts are threaded and are capped with nuts H which'are employed for drawing the ring outward. It has been Positioned found convenient to fashion the upper edge of-the ring flange. with a smallpart for maintaining the metal washer G in position.

When the parts are properly associated and a tight joint is to be effected, it is only necessary to draw the gasket member outward with the nuts Hf thereby forcibly squeezing the metal washer or packing between the outer face of the nipple and the relatively long inclined face of the rib C effecting thereby a positive airtight and gas-tight seal between the two members, one that is not effected by acids or other substances which would tend to destroy certain types of packing.

While metal is referred to as the packing, it. is to be understood, however, that the invention is not limited in its useful application, to a metal washer. The advantage, however, is quite apparent, when metal is desired to be used.-

In devices of this kind heretofore suggested the gasket or ring has usually been flat, and serious trouble hav .been encountered owing to the variations in the points of surface contact for the packing. These flat rings would often be bent or twisted and there would be a'tendency for an unequal application of the pressure at all' points. By the addition of the flange at the inner part of the ring the latter is materially stiffened so that the pressure necessary for completing a uniform seal at all points can be exerted throughout the ring without the heretofore objectionable tendency of the ring to spring or bend.

In Fig. 8 there is shown a slightly modified formof flanged gasket or ring, one de- 1 signed more particularly for use in connec tion with that type of bowl wherein the internal flange is employed, z. 6., a flange on.

the bowl stem designed to enter the coupling of the soil pipe. The soil pipe in this arrangement is in many cases made of lead. The bowl part in this modified form is indicated at I and the internal flange at K. This flange has an inclined outer face, as at 7a.. The lead .pipe is indicated at A and its upper edge is bent over outwardly directly above the flange L of the ring or gasket L. In this position the bent over edge of the pipe is in contact with the inclined surface of the flange K and is forcibly positioned against the outstanding flange of the bowl part. By drawing up the gasket L the overturned edge of the nipple is with equal force throughout brought into sealing contact with the bowl part and therequisite' seal thereby efiected- The other portions of the gasket adjusting and holding meansare the. same as in the other figure.

By the above construction it will be observed that upon tightening up the gasket,

thepacking is forced, through wed ging action, into close contact with the parts, and so throughout the entire circumference of the nipple.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is 1. The combination with a support, of a bowl member having an outstanding reinforced flange part at its base provided with a depending marginal supporting rib, a portion of the reinforcedpart'of the bowl flange adjacent the bowl formed with a relatively long inclined annular surface positioned laterally beyond the plane of the outlet of the bowl, a securing member fastened to the support, means for securing the flange part of the bowl to said member, and a nipple having a portion disposed within the space formed by the reinforcing flange, a ring shaped gasket surrounding the nipple and provided with a projecting rib, a sealing substance interposed between the relatively long inclined portion of the bowl flange, the projecting rib of the gasket and the nipple for tightly sealing the joint between the bowl and the nipple, and means for adjusting the gasket for forcing the sealing sul stance in position.

2. The combination with a support, of a bowl member having an outstanding flange at its base provided with a surrounding supporting rib and having intermediate the bowl and the rib an annular inclined surface arranged below the plane of the outlet of the bowl, a securing plate, means for locking the flange part of the bowl to the base, a nipple member entering the chamber formed by the flange and rib, a ring gasket located within the said chamber and having an upstanding rib part at its inner edge position adjacent the said inclined portion of the bowl flange, said upstanding rib having a depression in its edge,a packing mem-- ber interposed between, said inclined part and upstanding rib, and means on the ring for drawing the said upstanding rib part outwardly toward the inclined portion whereby the packing is pressed between the end of the nipple and the inclined portion for the purpose specified.

' In testimony whereof I hereunto afllx my signature in the presence of two witnesses.
